SMOKE-CHAMBER LINING.

Application filed January '26, 1927. Serial No. 163,627.

The object of my invention is to providemeans to permit the readyconstruction of a smoke chamber above a fireplace in communication witha chimney flue, whether the greater diameter'ol the flue be parallelwith the greater diameter of "the fireplace or at right angles thereto,whereby the masonry,

brickwork orthe like may be built up along the sides of the smokechamber in a proper manner and the sidewalls of the smoke chamber willbe smooth. p

In carrying out m j'invention I provide plates to belocated within themasonry or brickwork over a fireplace to 'provide the side walls of asmoke chamber, with a collar adapted to be attached to the upper ends ofsaid plates to register with a chimney flue whereby said plates aresecured together to .per1nit the building of the masonry therearound,whereby to provide a smoke chamber above the fireplace of the chimney,the plates serving as a lining for the sides of the smoke chamber. Afeature of my invention is thatthe smoke chamber plates are pro- "videdat their upper ends with sections-detachably secured to the plates andof such dimensions respecting the collar that When the latter is toregister with a'flue that is parallel with the longest dimension of thefireplace the sections willfibe detached from the plates and thelatterwill be attached to the collar alongthe narrow dimensions of thelatter. whereas when the greatest dimen sion of the flue is at arightangle to the. greatest dimension of the fireplace the plates withthe attached sections will be secured to the collaralong the greatestdimension of the latter. In either case the masonry may be built aroundthe smoke chamber plates as desired.

A further feature of the invention isthat the lower ends of the smokechamber plates are located at an angle with respect to the planes of theplates so as to be fitted over or against the upper portion of a damperlocated in an ordinary way within the masonry over the fireplace wherebythe smoke chamber plates will be sustained by the masonry or damper.

My invention comprises novel details of improvement that will be morefully here inafter set forth and then pointed out in the claims. I 7

Reference to be had to the accompanying drawings forming a part hereof,wherein Fig. 1 is a partly broken front view illustrating my improvementin a fireplace;

Fig. .2 is a vertical section;

Fig. 3 'is a perspective View illustrating the parts of my improvement"in position for use in a fireplace according to Fig. 1, and

Fig. 4L illustrates my improvement for use with the greater diameter ofa flue at right angles to the greater diameter of the fireplace. I p ,7

Similar numerals of reference "indicate corresponding parts in theseveral views.

The smoke chamber plates indicated at 1 and 2 may be made of sheet metaland detachably connected at their upper ends with a collar 3 which isadapted to register with a chimney flue. I have indicated a chimney fluelining at t but the flue may be built directly in the masonry forbrickwork of a chimney in any well known Way. The collar 3 is shownrectangular in shape, longer than wide, to correspond with the usual Thesmoke dimensions of chimney v fl'ues. chamber plates 1 and 2 divergedownwardly from the "collar 3 to provide the side walls of the smokechamber 5 in an upwardly converging manner above the fireplace 6, forwhich purpose the upper edge portions 1 2 of the plates 1 and 2 are'bentat an angle the adjacent portions of the collar 3 in a verticaldirection. The end portions 1 '2 are provided with holes to receivebolts 8" that pass through 'holes 9 the collar for securing the collarand platesftogether. The

collar may be made of a suitable piec'e'of metal'bent to the desiredrectangular shape providing outwardly disposed flanges 3 to be embeddedin the brickwork or masonry of the fireplace, (Figs. 1 and 2), to aid insupporting the lining 1 and in supporting the plates 1 and 2. The upperend portions of the smoke chamber plates 1 and 2 are provided withdetachable sections 1", 2", shown in triangular form, having their basesadjacent to the collar and their apices adjacent to a side edge of thecorresponding smoke plate. The sections 1 2 are shown having their outeredges substantially parallel with the corresponding outer edges of theplates 1, 2 and their inner angularly disposed edges opposingcorresponding angularly disposed edges 1, 2 of the plates 1. 2., wherebythe sections and plates are fitted edge to edge. The sections are shownproto theplane of the plates so to bearagainst 3 When the sections 1", 2are removed from the plates 1, 2 the width of the upper ends of theplates will be approximately the same as the width of the narrow ends ofcollar 3 so thatthe plates will be attached at their upper ends alongthe said ends 01 the collar to be fitted inthe fireplace with thegreatest length oi the collar extending in the direction of or parallelwith the greatest length ofthe fireplace, and with the plates 1v and 2diverging downwardly, as illustrated in Fig. 1. lVith the sections 1*,2" attached to the plates 1 and 2 the complete width of the sectionswith their plates will be approximately equal to the greater length ofthe collar, t), so that when the collar and the plates are locatedwithin the chimney the greater length of the collar will extend in adirection substantially at right angles to the greater length of thefireplace with the'plates 1, 2 diverging downwardly.

The lower ends of the plates 1, 2 may be rested upon the masonry orbrickwork, or may be fitted in conjunction with a fireplace damper ofany desired or well known variety, indicated at 12. The lower endportions 1, 2 of the plates 1, 2 are shown extendng at an angle to theplane of the plates, such. portions of the plates being adapted to beadjacent to the top edge oi the damper and spaced wider than the damperso as to extend slightly outside of the ends of the damper at the top tobe rested upon the masonry or brickwork in a substantially Verticalposition in such a way that the damper plate or valve 12* may swingwithin the portions 1, 2 of the smoke plates, as illustrated in Fig. 1,and the smoke will be conducted from the fireplace or the damper betweenthe smoke plates up to the chamber therein above the fireplace,communicating with the flue, having upwardly converging side wallsserving to aid in creating an upward draft to the flue and to resist thedeposit of soot. The construction described assures a smooth interior atthe sides of the smokechamber at the ends of the bricks outside thereofof proper shape causing proper alignment of the flue lining, thereby 1preventing a mason from inaccurately installing bricks along the portionof the fireplace or flue just above the fireplace.

Having now described my invention .what

I claim is 1. A fireplace smoke chamber lining comprising a collarhaving greater length than width, a pair of plates adapted .to besecured thereto at the upper ends, the collar being arranged toregisterwith a chimney fine with the plates diverging downwardly fromthe collar, the plates being provided with detachable sections at theupper por tions alongcorresponding edges, andlmeans fordetachably'securing the sections to the plates, whereby the plates andsections may be secured to-the greater length of the collar' and theplates without the sections maybe secured to the lesser width of thecollar.

2. A fireplace smoke chamber lining asset forth in claim 1, in which thesections have outer edges substantially parallel with corjacent theretobeing located at an angle to the first named edges of the plates.
